Platon Plastic Tube VA Meter – Overview The Platon GR/GRV flowmeters are moulded plastic tube variable area meters with ball floats. The precision moulded tapered tube has guides to stabilise the float, allowing easy flow reading against the clear 50mm long scale. Units are available calibrated for air or water flows. Typical applications are for operator monitoring of cooling, purging or sample flows. The GRV option has a built-in multi-turn flow control valve for simple adjustment of flow rates. Designed for vertical mounting on a control panel, the flowmeter is supplied with brackets for flush mounting through a cut-out of approximately 116 x 19mm. Alternatively, the meter can be surface mounted. For an immediate indication of process alarm conditions, adjustable transparent indicators can be clipped into the flowmeter face, presenting a red limit line at the required flow rate. These accessories can be used to show the limits of normal flow adjustment or an alarm level. Reliable and rugged process connections are made to stainless steel 1/8 NPT female threads built into a stainless backplate within the meter. The polycarbonate body and flow tube are O-ring sealed to the backplate, and can simply be disassembled for any necessary cleaning or interchange of flow scales.
